Rehabilitation and Dam Safety
Some dams will need rehabilitation to remain safe and protect the people
that live or work downstream. It is estimated that $200 million will be
required to rehabilitate the existing high hazard dams to comply with
federal and state dam safety laws.
More dams will become high hazard as long as residential and business
development is allowed below the dam and in the breach flood area.
NRCS assistance is available to project sponsors in rehabilitating flood
control dams with 65 percent federal cost-share and technical assistance.
Local project sponsors provide 35 percent of the rehabilitation costs.
Oklahoma has 2,107 flood control dams in 61
counties. These dam have been built in the
state through conservation districts with financial and
technical assistance from the Natural Resources
Conservation Service (NRCS), authorized through
Public Law 78-534, Flood Control Act of 1944
(Washita River Watershed) and Public Law 83-566
Watershed Protection and Flood Prevention
Program.
The primary purpose of flood control dams is to
reduce flooding. The secondary benefits of the dams
address a myriad of natural resource issues such
as soil erosion, water quality, animal waste
management, irrigation water management, water
supply, wetland development or enhancement, fish
and wildlife habitat and recreation.
Watershed projects also include conservation
practices such as terraces, waterways, ponds, gully
control, and pasture and rangeland plantings.
Operation and Maintenance of Dams
The annual operation and maintenance of dams is a
major responsibility for project sponsors (local units
of governments such as conservation districts).
Operation and maintenance of dams can be
expensive and labor intensive, but is necessary to
ensure dams function as they were designed and
remain safe. Maintenance work includes clearing
trees from dams and spillways, repairing erosion
damage, repairing damage to dams and spillways
following heavy rainstorms and keeping inlet towers
cleared of debris.
Operation and Maintenance Needs
$22 million is needed to meet the operation and
maintenance needs of the 2,107 flood control dams
in the state for fiscal years 2012-2016.
Annual Benefits
The 2,107 flood control dams and conservation
practices in the watershed projects provide an
estimated $82 million in annual benefits. Listed below
are the average annual benefits from watershed
projects that are located in Mayes and adjoining
counties.
